Current Space Weather Conditions A single period of geomagnetic storming reaching the G3 (Strong) level was observed overnight. Since that time, geomagnetic activity has been on the decline as the CME influence has continued to weaken. No further significant activity … Continue reading →

2012-09-03 15:14 UTC G2 (Moderate) Geomagnetic Storm in Progress G2 (Moderate) geomagnetic storming is ongoing now as a result of the coronal mass ejection (CME) arrival associated with the August 31st filament eruption. Continued geomagnetic storming is expected in the near term … Continue reading →

The launch of an Atlas V carrying NASA’s Radiation Belt Storm Probes (RBSP) payload was scrubbed today due to weather conditions associated with lightning, as well as cumulus and anvil clouds. With the unfavorable weather forecast as a result of … Continue reading →

Volcano and Aurora in Iceland Image Credit & Copyright: Sigurdur H. Stefnisson Explanation: Sometimes both heaven and Earth erupt. In Iceland in 1991, the volcano Hekla erupted at the same time that auroras were visible overhead. Hekla, one of the … Continue reading →

This image taken by SDO’s AIA instrument at 171 Angstrom shows the current conditions of the quiet corona and upper transition region of the Sun. Active Region 1515 released an M6.9 class flare beginning at 12:23 PM EDT and peaking … Continue reading →

EIT 304 A large solar flare yesterday triggered a coronal mass ejection travelling at 1400 km/s that will reach Earth today. An energetic eruption of this level can disrupt satellites, so operation teams at ESA and other organisations are closely … Continue reading →

Wiki Growth Over Time This is a project conducted by ChrisDavis and IgorNikolic to visualize the growth of wiki.tudelft.nl since its beginning in late 2004. Since then, it has grown to over 10,000 pages, and is now part of the … Continue reading →

The Living With a Star (LWS) program emphasizes the science necessary to understand those aspects of the Sun and the Earth’s space environment that affect life and society. The ultimate goal is to provide a predictive understanding of the system, … Continue reading →

The Sun Now– EIT (Extreme ultraviolet Imaging Telescope) images the solar atmosphere at several wavelengths, and therefore, shows solar material at different temperatures. In the images taken at 304 Angstrom the bright material is at 60,000 to 80,000 degrees Kelvin. … Continue reading →
